In my own experience—which may be accidental, not symptomatic—the number
of oddly coloured birds has been quite unusual. I have heard of albinos in many species, in many places ; and this week on the South Coast came upon the haunt of a black snipe, a very unusual extreme of melanism. It will probably be shot " in the interests of science ;" such is the reward of abnormality. Indeed, very
often birds themselves mob their queerly coloured brothers.
